Description

Technical Field

[0001] The invention relates to the field of garbage disposal, in particular to an in-pipe mud cleaning device for distributing sludge on an incinerator and a garbage incinerator. Background Art

[0002] my country is a populous country that generates a large amount of domestic waste every year. Currently, waste incineration power generation is the best way to dispose of domestic waste, and it is of great significance to achieve waste reduction, harmlessness and resource utilization.

[0003] In the waste incineration power generation process, the waste incinerator not only burns domestic waste, but also burns sludge with a certain moisture content and process waste with a certain calorific value in a certain proportion, which not only ensures the efficient combustion of the incinerator, but also can process a variety of solid wastes.

[0004] At present, the typical way to put sludge into the incinerator is to use the sludge distribution pipe that is uniformly distributed into the garbage incinerator to feed the material to the feeding grate and the top of the incineration grate in the incinerator. This feeding method makes the combustion condition in the incinerator optimal. However, due to the characteristics of non-Newtonian fluids and the viscous physical properties of the sludge itself, the sludge will adhere to and clog the pipeline after running for a period of time or the sludge in the pipeline is left to stand for a period of time. The adhesion and clogging of the sludge on the inner wall of the pipeline will inevitably have a great impact on the uniform feeding of the sludge. Many of the current uniform distribution pipelines do not have corresponding measures to solve the problem of sludge adhesion and clogging in the sludge uniform distribution pipeline. If the sludge adhesion and clogging in the pipeline occurs, only complex solutions can be adopted.

[0005] Therefore, it is necessary to propose a new in-pipe mud cleaning device for sludge cloth on an incinerator and a garbage incinerator to solve the problems in the prior art. Summary of the invention

[0006] A series of simplified concepts are introduced in the Summary of the Invention, which will be further described in detail in the Detailed Description of the Invention.

[0007] The present invention provides a device for cleaning mud in a pipe for distributing mud on an incinerator, comprising:

[0008] A feed pipe extending along a first direction for inputting sludge;

[0009] A mud cleaning device, comprising a mud cleaning spiral arranged in the feed pipe and extending along the first direction and a driving device driving the mud cleaning spiral to rotate around an axis.

[0010] Exemplarily, the mud cleaning screw includes a solenoid coil extending along the first direction and winding in a spiral shape.

[0012] Exemplarily, the mud cleaning device further includes a screw rack disposed at both ends of the mud cleaning screw, and the screw rack fixes the mud cleaning screw.

[0013] Exemplarily, the spiral clamp is configured as a tripod, and the three leg ends of the tripod are located on concentric circles of the cross section of the feed pipe.

[0014] Exemplarily, the diameter of the concentric circles is less than or equal to the diameter of the feed pipe.

[0015] Exemplarily, the cross-section of the mud cleaning spiral is set to be trapezoidal.

[0016] Exemplarily, the shorter base of the trapezoid is arranged on the inner side of the mud cleaning spiral, and the longer base of the trapezoid is arranged on the outer side of the mud cleaning spiral.

[0017] Exemplarily, a control device is used to control the frequency and / or time of the driving operation of the driving device.

[0027] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0028] In order to fully understand the present invention, a detailed description will be provided in the following description to illustrate the in-pipe mud cleaning device for sludge distribution on the incinerator and the garbage incinerator of the present invention. Obviously, the implementation of the present invention is not limited to the specific details familiar to those skilled in the field of garbage disposal. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention can also have other embodiments.

[0029] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0030] In the waste incineration power generation process, the waste incinerator not only burns domestic waste, but also burns sludge with a certain moisture content and process waste with a certain calorific value in a certain proportion, which not only ensures the efficient combustion of the incinerator, but also can process a variety of solid wastes.

[0031] like Figure 1As shown, a schematic diagram of the structure of a waste incinerator according to an embodiment is shown, wherein the waste incinerator includes a feed port 1, a feeding grate 2, a burning grate 3, a primary air supply system 4, a secondary air supply system 5 and a slag discharge port 6. After the waste enters the incineration power plant, it is input into the incinerator from the feed port 1, and the feeding grate 2 pushes the waste material to the burning grate 3. During the incineration process, the primary air supply system 4 supplies primary air to the burning grate to assist combustion, and the flue gas generated by the combustion is further burned under the secondary air provided by the secondary air supply system 5, and the ash generated by the combustion is discharged from the slag discharge port 6. In the process of waste incineration, sludge with a certain moisture content is often mixed and burned. At present, the typical method of feeding sludge into the incinerator is to use a sludge distribution pipe that is evenly fed into the waste incinerator to feed the feed grate and the burning grate in the incinerator. This feeding method makes the combustion condition in the incinerator optimal. Figure 1 As shown, a sludge dispensing device 7 is provided above the feeding grate 2 and the burning grate 3 of the incinerator to feed the burning grate 3 and the feeding grate 2. Figure 2 , shows a schematic structural diagram of an in-pipe mud cleaning device for sludge distribution according to an embodiment, wherein the in-pipe mud cleaning device 100 for sludge distribution includes a feed pipe 101 and a discharge pipe 102, the feed pipe 101 is used to input sludge, and the discharge pipe 102 is connected to the feed pipe 101 and is arranged to distribute sludge into the incinerator. Figure 2 As shown, the sludge enters the feed pipe 101 from the direction indicated by the arrow A. By continuously inputting the sludge into the feed pipe 101, the sludge is distributed in the incinerator one by one through the discharge pipe 102 below the feed pipe 101 (as shown in FIG. Figure 2 In the direction indicated by the arrow B), a flow regulating mechanism is also connected between the discharge pipe 102 and the feed pipe 101 to adjust the sludge input speed.

[0032] Due to the characteristics of non-Newtonian fluids and the viscous physical properties of the sludge itself, the sludge will adhere to and clog the pipe after running for a period of time or the sludge in the pipe is left to stand for a period of time. The adhesion and clogging of the sludge on the inner wall of the pipe will inevitably have a great impact on the uniform distribution of the sludge. Many current uniform distribution pipes do not have corresponding measures to solve the problem of sludge adhesion and clogging in the sludge uniform distribution pipes. If the sludge adhesion and clogging in the pipe occurs, only complex solutions can be adopted.

[0033] Embodiment 1

[0034] In order to solve the above technical problems, the present invention provides a sludge cleaning device for distributing sludge in a pipe on an incinerator, comprising:

[0035] A feed pipe extending along a first direction for inputting sludge;

[0036] A mud cleaning device, comprising a mud cleaning spiral arranged in the feed pipe and extending along the first direction and a driving device driving the mud cleaning spiral to rotate around an axis.

[0037] See also Figure 3 , shows a schematic structural diagram of an in-pipe mud cleaning device for sludge cloth according to an embodiment of the present invention, which is shown in Figure 2 A mud cleaning device 200 is added to the in-pipe mud cleaning device 100 for distributing the mud material in the pipe.

[0038] It should be understood that in this embodiment Figure 2 The mud cleaning device 200 is arranged in the in-pipe mud cleaning device 100 for sludge distribution material in the present invention is merely exemplary, and the mud cleaning device 200 of the present invention is applicable to any in-pipe mud cleaning device for sludge distribution material having the above-mentioned feeding pipeline.

[0039] See also Figure 3 The in-pipe mud cleaning device for sludge spreading material comprises a feed pipe 101, which extends along a first direction (length direction) and is used to input sludge into the in-pipe mud cleaning device for sludge spreading material.

[0040] According to the present invention, the in-pipe mud cleaning device for the sludge cloth includes a mud cleaning device such as Figure 3 As shown, the mud cleaning device includes a mud cleaning spiral 201 disposed in the feed pipe 101, and the mud cleaning spiral 201 extends along a first direction (the length direction of the feed pipe 101).

[0041] The mud cleaning device further comprises a driving device 202 for driving the mud cleaning screw 201 to rotate around an axis.

[0042] The mud cleaning spiral 201 can be any spirally arranged device, including spiral blades arranged along a vertical axis, a spirally wound solenoid, such as a DNA spiral chain structure, etc., which is not limited here.

[0043] The driving device 202 includes a motor or a reducer, the shaft of which is connected to the rotating shaft of the mud cleaning screw to drive the mud cleaning screw to rotate around the shaft.

[0044] The axial rotation of the sludge cleaning spiral 201 promotes the sludge to move in the feed pipe in the input direction to avoid sludge blockage. On the other hand, the spiral shape loosens the sludge in the feed pipe to prevent sludge blockage in the feed pipe, thereby cleaning the sludge.

[0045] Exemplarily, the cleaning spiral is configured as a spirally wound solenoid extending along the first direction.

[0046] See also Figure 4A schematic structural diagram of a mud cleaning device 200 according to an embodiment of the present invention is shown.

[0047] like Figure 4 As shown, the mud cleaning spiral 201 is configured as a solenoid coil that is spirally wound.

[0048] The sludge cleaning spiral 201 is configured as a spirally wound solenoid, wherein the hollow structure provides a path for the sludge input, so that the sludge cleaning spiral 201 occupies a small space, thereby avoiding affecting the input rate of the sludge. When the sludge cleaning spiral rotates around the axis, the spiral structure has the effect of scraping the surrounding sludge, thereby removing the sludge adhering to the pipe wall, avoiding the sludge from adhering to the feed pipe during the input process, and achieving a better sludge cleaning effect.

[0049] In one example according to the present invention, the outermost side of the mud cleaning spiral 201 is in contact with the wall of the feed pipe 101, such as Figure 3 As shown, the diameter of the solenoid of the helically wound sludge cleaning spiral 201 is equal to the diameter of the feed pipe 101, so that the outermost side of the solenoid fits against the wall of the feed pipe. This can clean the sludge on the wall of the pipe in real time during the process of inputting sludge into the feed pipe 101, further improving the sludge cleaning effect.

[0050] In one example according to the present invention, the cross section of the helically wound mud cleaning spiral is set to be trapezoidal. Figure 5 , shows a schematic structural diagram of a mud cleaning screw according to an example of the present invention, wherein the dotted line shows a schematic cross-sectional structural diagram of the mud cleaning screw.

[0051] like Figure 5 As shown, the cross section of the mud cleaning spiral 201 is set to be trapezoidal, so that the two ends of the cross section of the mud cleaning spiral are blade-shaped. During the rotation of the mud cleaning spiral around the axis, the blade-shaped mud cleaning spiral scrapes the side wall of the feed pipe 101 more obviously, which is more conducive to removing the sludge adhering to the side wall of the feed pipe.

[0052] Further, exemplary, such as Figure 5 As shown, the shorter side of the trapezoidal cross section is arranged on the inner side of the mud cleaning spiral 201, and the longer side is arranged on the outer side of the mud cleaning spiral 201. Since the shorter side of the trapezoidal cross section is arranged on the inner side of the mud cleaning spiral 201, and the longer side is arranged on the outer side of the mud cleaning spiral 201, in the direction of sludge moving, the contact surface between the mud cleaning spiral 201 and the sludge is the side of the trapezoidal cross section, which increases the contact surface of the side of the mud cleaning spiral 201 contacting the sludge, can play the effect of boosting the sludge to assist the sludge to move forward, and further prevent the sludge from being blocked in the feed pipe.

[0053] Continue to view Figure 3 and Figure 4, illustratively, spiral racks 203 are provided at both ends of the mud cleaning spiral, and the mud cleaning spiral 201 configured as a solenoid is spirally wound around the spiral racks 203 , and the spiral racks 203 are used to fix the mud cleaning spiral 201 .

[0054] A spiral frame is provided, which, on the one hand, provides a spirally wound axis around which the mud cleaning spiral 201 configured as a solenoid is spirally wound, and the driving device 202 is connected to the mud cleaning spiral 201 via the spiral frame 203, so that the mud cleaning spiral 201 can rotate around the axis, and on the other hand, the spiral frame 203 can also fix the mud cleaning spiral 201 in the feed pipe 101 to prevent the solenoid from being squeezed by the sludge input into the feed pipe 101 and deviating from the rotating axis, thereby ensuring the mud cleaning effect.

[0055] In one example according to the present invention, Figure 4 As shown, the spiral frame 203 is configured as a tripod, and the three legs of the tripod are located on the concentric circles of the feed section. The three legs of the tripod are configured to be located on the concentric circles of the feed pipe, further preventing the feed spiral from deviating from the rotation axis. At the same time, the three legs of the tripod stir the sludge input into the feed pipe 101, thereby achieving a distribution effect on the sludge input into the feed pipe 101.

[0056] In one example according to the present invention, Figure 4 As shown, the diameter of the concentric circles where the three legs of the spiral clamp 203 arranged as a tripod are located is less than or equal to the diameter of the feed pipe.

[0057] In one example according to the present invention, a control device is further included to control the driving device to perform driving operation. Under the control of the control device, a predetermined cleaning frequency and cleaning time can be set so that the mud cleaning device periodically performs mud cleaning operation. For example, the control device is set to run the motor for 30 minutes every 6 hours, so that the mud cleaning device performs a mud cleaning operation. This prevents sludge drying in the feed pipe from clogging the feed pipe and adhering to the side wall of the feed pipe.

[0058] Embodiment 2

[0059] The present invention also provides a garbage incinerator, comprising the in-pipe mud cleaning device for distributing mud on the incinerator as described in the first embodiment.

[0060] Since a mud cleaning device for cleaning the sludge in the feed pipe is provided in the in-pipe mud cleaning device for spreading sludge on the incinerator according to the present invention, the mud cleaning spiral therein, when rotating around the axis, promotes the sludge to move in the feed pipe in the input direction to avoid sludge blockage, and on the other hand, the spiral shape loosens the sludge in the feed pipe to prevent sludge blockage in the feed pipe, thereby cleaning the sludge. In the waste incinerator according to the present invention, blockage of the mud cleaning device for spreading sludge is avoided, and during the incineration process, uniform sludge dropping can be continuously achieved, thereby achieving stable and sustainable operation of the waste incinerator.

[0061] The present invention has been described by the above embodiments, but it should be understood that the above embodiments are only for the purpose of example and description, and are not intended to limit the present invention to the scope of the described embodiments. In addition, it can be understood by those skilled in the art that the present invention is not limited to the above embodiments, and more variations and modifications can be made according to the teachings of the present invention, and these variations and modifications all fall within the scope of the protection claimed by the present invention.
